Call Detail Recording (CDR) / Station Message
Detail Recording (SMDR)
With Call Detail Recording activated for the incoming trunk groups, you can
monitor the number of calls into your automated attendant ports. See also
‘‘Security Violation Notification Feature (DEFINITY ECS and DEFINITY G3 only)’’
on page 4-57.
NOTE:
Most call accounting packages discard this valuable security information. If
you are using a call accounting package, check to see if the information you
need can be stored by making adjustments in the software. If it cannot be
stored, be sure to check the raw data supplied by the CDR.
Review CDR for the following symptoms of automated attendant abuse:
 Short holding times on any trunk group where automated attendant is the
originating endpoint or terminating endpoint
 Calls to international locations not normal for your business
 Calls to suspicious destinations
 Numerous calls to the same number
 Undefined account codes
NOTE:
For DEFINITY G2 and System 85, since the CDR only records the last
extension on the call, internal toll abusers transfer unauthorized calls to
another extension before they disconnect so that the CDR does not track
the originating station. If the transfer is to your automated attendant system,
it could give a false indication that your automated attendant system is the
source of the toll fraud.
For DEFINITY ECS, DEFINITY G1, G3, and System 75:
 Display the Features-Related System Parameters screen by using change
system-parameters
feature (G1 and System 75 only) or change
system-parameters cdr feature (G3 only).
 Administer the appropriate format to collect the most information. The
format depends on the capabilities of your CDR analyzing/recording
device.
 Use change trunk-group to display the Trunk Group screen.
 Enter y in the SMDR/CDR Reports field.
For DEFINITY G2:
 Use PROC275 WORD1 FIELD14 to turn on CDR for incoming calls.
 Use PROC101 WORD1 FIELD8 to specify the trunk groups.
